Pipe Keepers is a citizen science program to address the threat of stormwater pollution
entering Lake Tahoe. Runoff from storms and snowmelt is the largest source
of pollution that degrades Lake clarity. League staff will train you to survey
local neighborhoods and collect stormwater samples during rain and snowmelt
events.

The first step is to attend a Pipe Keeper Training to learn how
to monitor stormwater infrastructure. Trained volunteers will then
conduct monthly monitoring of assigned pipes to report any issues and help
prioritize the most polluting pipes. Volunteers can also participate in
stormwater sampling efforts to collect turbidity data during the most critical
storms and snowmelt events.
